new and Improved Charge iupplyinp Means for Internal-Combustion the following is scri tion.

1 is invention relates to certain improvements in. charge supplying means for internal more particularly to means forforcing the air and liquid or gaseous fuel either separatcl or together undernv state of compression lnto the cylinder and at equal pressures; the present apilit'atioi'l being a division of my application i Serial No. 300,997, filed l ebruary 14., 1906, Patent No. 868,678, for rotary engine, granted October 22, 1907.

' The invention consists in certain features of construction and combination of parts, all of which will be fully set forth hereinafter and particularly pointed out in the claims.

'lteference is to be had to the accompanyin drawings, forniin a part of this specification, in which sirni ar characters of refer ence indicate corresponding parts in both the figures, and in which Engines, of which a full, clear, and exact de- Figure l is a side elevation of a. portion of. rotary engine provided with my improved 2 1s a veralr tank.

The tank s provided with a suitable drawoll' faucet'1'5 ad'aceut the bottom thereof, whereby the fuci chamber Inn and may also be provided wit: a faucet 16 communicating with the air compartment 13 just above 1.1 ie compartment 12, whereby an moisture of condensation may be drawn 0 Specification of Letters Patent.

Patented. June e, 1908. Divided and this application filed June 26, 190?.

The device is provided with a suitable filling pipe 17 having its inner end terminating in the compartment 12, and havin asuit-able valve. 18, whereby the pipe may e normally kept closed. The air compartment may be provided with a suitable ga e 19, whereby the pressure may be readily etermined, andmay also be provided with any suitable form of safet valve 20 to prevent the generation. of too hig a ressurc within the compartment.

The tanli above described is connected by separate conduits leading fromtheair chamher and the liquid chamber to the inlet valve of the engine, and in connection with these conduits is an air pump operated by the engine to maintain the air and liquid under pressure and deliver them at the same pressure to the engine. A liquid pump is also provided for use in pumping the liquid, if desired.

To more clearly set forth the operation. of my improved means, I have illustrated a portion of a rotary en upon suitable braces 22 and having a rotary shaft 23 extending outwardly through one aided the casing; Mounted upon this shaft is a gear wheel 24 intermeshing with a inion 25, through the instrumentality of w iioh thetwo um smay beoperated. As shown, the she; t 2 3 is the main shaft of the engine, and the pinion 25 is either the same size as the gear wheel 24, or the size of one is a the other, the rela: 'tive sizes of the two number of inlet-valves an the ra 'idity with w 'ch it isdesiredto operate t epumps'. Pivotal] mounted upon the shaft 23 is an arm 26 avin linkconnections 27 and 28 to the piston to s 29and 30 of the two pumps 31 and.32. The iston rod or the connecting link of one o the pumps is operatively a link 33 to a disk 34 carried by'the pinion 25. imparts a, reciprocating motion to the rd 29 of one pum and through the. link 27, the arm 26, and t e link 28, also imparts a reciprocating motion to the piston of the other pump. The relative sizes of the two pumps 31 and 32 mav be determine'd upon according to the rela tive pro ortions .of liquid and air which it is 'desiret to deliver to the engine. As shown, the piston rod 29 has a shorter stroke than the piston rod 30, and the pump 31 is accordingly shown as shorter.

gine 21, supported 3 de ending upon the The rotation of the pinion piston 10c implication above referred to.

Communicating with the pumps and also with the tank 10, there are rovided a fuel delivery pipe 35 and an air elivery ipe 36 in communication with the inlet valves of the engine, as clearly set forth in my prior s shown, t e fuel pipe 35 is connected to the lower portion of t 1e fuel tank by a branch conduit 37, having two check valves 38 and 39 located therein. Intermediate the check valves, a branch ooduit 40 leads from the conduit 37 to the fuel pump 31 and is provided with a hand valve 46. The air delivery conduit 36 leading to the inlet valve-is connected to the therein. of air from the storage tank to 30 1 provide a conduit 47 having upper portion of the tank 10 by a branch condult 41 having check valves 42 and 43 and hand-controlled valves 44 and 45 located For permitting the direct delivery the conduit 36,

trolled valve 48 and a check v 4 Any suitable means may be employed for creatmg air pressure within the compressed air chamber 13, as, for instance, an operating pum 50 connected'thereto by a suitable con uit 51. In the operation of my improved charge-su plying means, a suit-able ressure is createri m the air chamber and the uel chamber communicating therewith b means of the hand-controlled pump 50. A ter the en ine is started this pump is no longer nee ed, and'the air urnp 32 on the engine serves to take air 30m the atmosphere and deliverit through the conduit 41 and valves 42 and 45 into the air chamber. The valve 44 is normally closed, as is also the valve 46. A portion of the compressed air in the air chamber 13 passes tnrou h fuel chamber, and t e the pipe 14 into the liquid fuel passes out through the ipe 37 into the conduit 3.5 on its way to t e inlet valve of the engine; The air in the chamber 13 passes out through the conduit 47 into the conduit 36, ahd the air and liquid are thus delivered to the engine under identically the same pressure. continuously pumping air from the atm0sphere and com ressing it into the compression tank, am the compressed 'air forces itself andthc gasolcnc to the the pct-cock 52 of the pump 31 is open and the valve 46 is closed, whereby this pump does no work. By closing the valve 45 and opening the valve 44,,the air pump will then force the air direct to the engine.

from the atmosphere and the liquid pump 31 will have to be brought into 0 erationtosupply the fuel to the engine. The pet-coek 52 on the pum 31 is then closed and the valve 46 is opcnc so that the pump 31 draws liquid from the tank through the check valve 38 and the conduit 40, and forces it back through the conduit 40, check valve 39, and

a hand-con vs 49 therein.-

The pump 32 is engine while conduit 37 on its way to the engine. The pump 31 is used as a pump only in case of emer ency, as, for instance, an. air leak in cham er 13, and the pump 50 is used only in starting the device. The tank 10 can he used as a pressure tank to start the engine with compressed air, if desired, but the main or principal object is to have the air and the liquid fuel under compression in the tank 10, so that the compressed air will force itself and the gasolene up to the engine cylinder under equally balanced pressure and in proper proportion.
